Three ounces of cinnamon cost $2.40. if there are 16 ounces in 1 pound, how much does cinnamon cost per pound?

If its $2.40 for 3 ounces of cinnamon, you would divide that 2.40 by your 3 and get .8

so it's $0.80 for 1 ounce of cinnamon

if you then multiply that .80 by 16 you get your answer of 12.8

So It costs $12.80 to buy 1 pound of cinnamon
